Abstract
The utility model discloses a powder metallurgy bevel gear for transmission of a millstone motor. The powder metallurgy bevel gear comprises a gear body, wherein a tapered tooth surface for transmission is arranged on the gear body; and an annular groove for reducing the weight of the bevel gear is formed on the lower surface of the gear body. Thus, through the annular groove formed on the lower surface of the gear body, the weight of the bevel gear can be reduced to a largest extent; the uniformity of the whole density of the bevel gear can be ensured; the phenomenon of large energy consumption caused by local overweight in the working process can be avoided; the material is saved; and the cost and the energy consumption can be reduced.
Description
Technical field
The utility model relates to a kind of angular wheel, relates in particular to the powder metallurgy angular wheel that a kind of millstone motor transmission is used.
Background technology
At present, millstone motor all comes transmission with gear, especially with angular wheel use at most.In early, the angular wheel that the millstone motor transmission is used all is processed into by casting or steel part, and due to the restriction of technique itself, the precision of this early stage angular wheel is lower, and overall weight is bigger than normal.to present stage, along with the development of PM technique and universal, the angular wheel that existing millstone motor transmission is used is all made by PM technique, the powder metallurgy angular wheel that the millstone motor transmission is used has solved the lower problem of early stage angular wheel precision, overall weight problem bigger than normal has also obtained improvement to a certain degree, but, the powder metallurgy angular wheel that existing millstone motor transmission is used is not still realized loss of weight to greatest extent, and, also there is the inhomogeneous problem of global density, cause angular wheel to lay particular stress on and cause energy consumption larger due to the part in the course of the work.
The utility model content
For the deficiencies in the prior art, the powder metallurgy angular wheel that provides a kind of millstone motor transmission to use is provided the purpose of this utility model, and it has realized loss of weight to greatest extent, and global density is even.
The utility model adopts following technical scheme for achieving the above object:
The powder metallurgy angular wheel that a kind of millstone motor transmission is used comprises the gear body, is provided with the taper flank of tooth for transmission on described gear body, and the lower surface of described gear body is provided with one for the annular groove that reduces angular wheel weight.
Wherein, the outer gradient of described annular groove is consistent with the gradient of the taper flank of tooth.
The powder metallurgy angular wheel that a kind of millstone motor transmission that the utility model is set forth is used, its beneficial effect is: the utility model arranges annular groove by the lower surface at the gear body, reduced to greatest extent the weight of angular wheel, guaranteed the uniformity of angular wheel global density, can avoid occurring in the course of the work laying particular stress on because of the part the larger phenomenon of energy consumption that causes, therefore save material, reduced cost and energy consumption; In addition, the outer gradient of annular groove is consistent with the gradient of the taper flank of tooth, more is conducive to keep the uniformity of angular wheel global density and reduces the angular wheel energy consumption of transmission in the course of the work.
Description of drawings
Fig. 1 is the configuration diagram of the utility model embodiment.
Description of reference numerals:
10, gear body;
11, the taper flank of tooth;
12, annular groove.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment, the utility model is further described.
Please refer to shown in Figure 1, it has demonstrated the concrete structure of the utility model preferred embodiment, the powder metallurgy angular wheel that a kind of millstone motor transmission is used, comprise gear body 10, be provided with the taper flank of tooth 11 for transmission on described gear body 10, the lower surface of described gear body 10 is provided with one and is used for reducing to greatest extent the annular groove 12 of angular wheel weight.
And the outer gradient of described annular groove 12 is consistent with the gradient of the taper flank of tooth 11, so more is conducive to keep the uniformity of angular wheel global density and reduces the angular wheel energy consumption of transmission in the course of the work.
During work, because the lower surface at gear body 10 is provided with annular groove 12, reduced to greatest extent the weight of angular wheel, guaranteed the uniformity of angular wheel global density, can avoid occurring in the course of the work laying particular stress on because of the part the larger phenomenon of energy consumption that causes, therefore save material, reduced cost and energy consumption.In addition, the outer gradient of annular groove 12 is consistent with the gradient of the taper flank of tooth 11, more is conducive to keep the uniformity of angular wheel global density and reduces the angular wheel energy consumption of transmission in the course of the work.
The above, it is only the utility model preferred embodiment, be not that technical scope of the present utility model is imposed any restrictions, therefore every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any trickle modification, equivalent variations and modification that above embodiment does.
